Is this the right coil wire for a noob to buy in bulk ?

[Joshinthecity]

Seems to me this is the right middle-ground, starting-point.
But if there's one thing I know,
It's that I don't know jack about building coils.
yet.

That should work fine.

That says Kanthal, then it says Nichrome.

Kanthal is different than Nichrome.

The Kanthal I buy is Kanthal A-1.

ahh. I see.
I'll grab the one you suggested.
shipping $10 to Oz.
is 28 considered the noob-gauge ? I was under the impression I wanted 30.
Maybe both?

Here's a table I came up with for making pdib-standard 8 wrap micro coils:

An 8/7 wrap micro coil on a Reomizer 2:
26 AWG Nichrome 60 = 0.5Ω @ 0.1272" wide
based on the above:
26 AWG Kanthal A1  = 0.6Ω @ 0.1272" wide
27 AWG Kanthal A1  = 0.8Ω @ 0.1136" wide
28 AWG Nichrome 60 = 0.8Ω @ 0.1008" wide
28 AWG Kanthal A1  = 1.0Ω @ 0.1008" wide
29 AWG Kanthal A1  = 1.2Ω @ 0.0904" wide
30 AWG Nichrome 60 = 1.3Ω @ 0.0800" wide
30 AWG Kanthal A1  = 1.6Ω @ 0.0800" wide
31 AWG Kanthal A1  = 2.0Ω @ 0.0712" wide
32 AWG Nichrome 60 = 2.0Ω @ 0.0640" wide
32 AWG Kanthal A1  = 2.5Ω @ 0.0640" wide

Different leg length could vary these ± 0.1Ω due to rounding.

A 1/16" drill bit is 0.0625". My 16 gauge filler needles are about 0.645" at least on my calipers. About the same.

If you are aiming for coils around .9 to 1.5 ohms the 28 is great. For higher ohms the 30 or 32 gauge. I use 32 gauge for coils around 2.2-2.4

Look up Temco on Ebay. They are probably cheaper!

I prefer 28g or 26g but 30g works awesome as well.

I have 100 foot spools of Kanthal A1, in even # gauges from 26 to 32, as well as some Nichrome 60. I'd recommend at least a spool each of 28 and 30 Kanthal A1. With a range of 7 - 9 wraps and varying coil diameter, you can get close to pretty much any resistance you'd want on a mechanical Grand.

26 is for getting down in the sub-ohm range, while 32 is better for ProTanks, etc. or if you want higher ohm coils for a VV Grand with higher voltage. IMO, it's too high of a resistance for a mechanical Grand.

Temco is undoubtedly the best source for US purchases. I don't know anything about their international shipping costs though. Maybe someone else can address that.

That table is a great resource

Thanks! There was a question about the 8/7 wrap coil designation when I originally posted it. 7 is the number of wraps on the drill bit between the legs, while 8 is the number you'd count 180º from the legs.
